At MWC 2025 in Barcelona, Lenovo debuted its latest prototype laptop that integrates solar charging capabilities directly into the lid. The "Yoga Solar PC Concept" utilizes photovoltaic cells with a 24% conversion efficiency rate and implements "Back Contact Cell" technology that positions mounting hardware behind the cells to maximize absorption surface. The device measures 15 mm thick and weighs 1.22 kg. The system employs a Dynamic Solar Tracking mechanism that monitors real-time power generation and automatically adjusts charging parameters to optimize energy capture regardless of lighting conditions. According to Lenovo's testing, 20 minutes of direct sunlight exposure generates sufficient power for approximately one hour of video playback.

Lenovo chose an unspecified Intel Core Ultra processor generation for the platform base, up to 32 GB RAM, 1 TB storage, and a 14-inch OLED display. Three USB-C ports allow for conventional charging when solar power is unavailable. Lenovo is also developing a separate Solar Power Kit accessory for Yoga devices. This peripheral includes a detachable solar panel with USB-C connectivity that charges external battery packs, which can later power laptops or other devices. No release timeline or pricing information has been announced for either product. However, this is a welcome development in the laptop space, which has maintained the tried-and-true formula of laptop design and functionality.
